TestDisk is a powerful free data recovery program! It was primarily designed to help recover lost partitions and/or make non-booting disks bootable again when these symptoms are caused by faulty software, certain types of viruses or human error (such as accidentally deleting your Partition Table). TestDisk can find lost partitions for all of these file systems: BeFS ( BeOS ) BSD disklabel ( FreeBSD/OpenBSD/NetBSD ) CramFS, Compressed File System DOS/Windows FAT12, FAT16 and FAT32 HFS and HFS+, Hierarchical File System JFS, IBM's Journaled File System Linux Ext2 and Ext3 Linux Raid RAID 1: mirroring RAID 4: striped array with parity device RAID 5: striped array with distributed parity information RAID 6: striped array with distributed dual redundancy information Linux Swap (versions 1 and 2) LVM and LVM2, Linux Logical Volume Manager Mac partition map Novell Storage Services NSS NTFS ( Windows NT/2K/XP/2003/Vista ) ReiserFS 3.5, 3.6 and 4 Sun Solaris i386 disklabel Unix File System UFS and UFS2 (Sun/BSD/...)
